What drove BJP to pull its Bankipur nominee days before Prashant Kishor face-off

BJP's Abhishek Kumar Sinha withdrew from the Bankipur bypoll citing family reasons. The party then fielded Neeraj Kumar Sinha as its new candidate for the contest. Opposition parties claimed the BJP was nervous about a potential defeat in the upcoming election. Jan Suraaj founder Prashant Kishor is campaigning against the ruling party. Polling for the Bankipur bypoll is scheduled for July 30.
